摘要： A collapsible hand saw features an elongated tubular frame member with a hollow interior that runs longitudinally therethrough. First and second arms are removably engaged to the tubular frame near first and second ends of thereof, to span outward from an underside thereof in a common direction. Each arm, near a distal mounting end thereof is configured for selective coupling to a bowsaw blade at a respective mounting hole therein near a respective end thereof. An adjustable tensioner is connectable between the frame member and the first arm, and when tightened, pulls the respective mounting end of said first arm away from the second arm and toward the first end of the frame member to tension the blade. The hollow interior of the frame member accommodates simultaneous storage therein of at least the first and second arms, the adjustable tensioner, and one or multiple blades.

摘要： The present invention relates to an extendable folding saw that is lightweight and compact when retracted yet rigid when extended. In one embodiment, the extendable folding saw can have a folding saw and a removably attached extension. The folding saw can have a grip and a pivotally attached saw. The extension can comprise several members that are compactable to a length not much greater than the length of the longest individual member. The members of the extension can have a generally I shaped profile. The extension rod can be attached to the folding saw in a snap-fitting manner for use. A retracted folding saw can be snapped side-by-side to a retracted to extension rod for storage.

摘要： A spider hub pole retaining assembly may include a hub, poles and a retainer. The hub may include channels extending radially outward in a plane. The poles maybe pivotably coupled to the hub near a center of the hub so as to be pivotable between a first position in which the poles extend radially outwardly through the channels in the plane and a second position in which the poles extend away from the outside of the channels. The retainer may include a top rotatably supported by the hub and hooks extending from the top. The top is rotatable between a retaining position in which the hooks receive the poles when the poles are in the first position and a releasing position in which the hooks are angularly offset with respect to the channels to facilitate withdrawal of the poles from the channels.

摘要： A portioning device for cutting or leveling a food product includes a blade configured to cut the food product, a first leg section and a second leg section configured to support the portioning device on a surface, and a handle section configured to be manipulated by a user. Each of the first and second leg sections include a leg, a blade holder configured to connect with the blade, and a leg lock operatively mounted to the leg and configured to selectively lock the leg in a position at a selected height of the leg to adjust a distance between the blade and the surface. The blade is a wire. The handle section is foldable about the central portion thereof to place the device in a collapsed configuration.

摘要： A pole saw includes a long handle with end adapter, a blade-carrying component pivoted to the end adapter for movement between an extended use position and a handle-adjacent storage position, and a saw blade fixed to the blade-carrying component. The end adapter and holding component are cast aluminum for strength and light weight, and are pivoted together about an offset axis so that the blade and blade-carrying component are positioned adjacent the handle in a partially protected position when collapsed for storage. A folding lock mechanism includes an anchor that engages a saw-holding bolt on the blade-carrying component, and a wing nut that can be tightened to secure the sheath on the blade.

摘要： There is disclosed a powered reciprocating table saw, for sawing large foam panels having embedded steel framing members, comprising a work table for supporting a workpiece on a top side of the work table and having a blade opening disposed through the work table proximate a central portion thereof. A saw motor is supported underneath the work table, the saw motor having a reciprocating output shaft extending from a housing of the motor, and blade clamping means disposed on the output shaft. An elongated saw blade is retained in the blade clamping means of the saw motor and positioned to move reciprocatingly through the blade opening to the top side of the work table for sawing the workpiece. In another aspect a motor mount is disclosed for attaching the saw motor to the work table. In yet another aspect a blade guide supported by the work table is disclosed, which limits sideways and rearward displacement of the saw blade while sawing the workpiece.

摘要： A handle assembly includes a handle body formed with a longitudinal blade receiving space, a coupling member mounted on the handle body within the blade receiving space and confining an insert slit aligned and communicated with the blade receiving space, and a locking unit extending movably and transversely through the handle body and having wider and narrower sections. The locking unit extends through the coupling member to permit pivoting of the coupling member relative to the handle body. The insert slit is adapted to permit extension of a saw blade thereinto via a front opening of the coupling member. The locking pin is movable between an unlocking position, in which the narrower section is registered with the insert slit to permit movement of the locking unit into and out of a locking hole of the saw blade, and a locking position, in which the wider section is registered with the insert slit for engaging the locking hole of the saw blade. The coupling member rotates with the saw blade between unfolded and folded positions. A positioning unit mounted on the handle body is operable to engage releasably the coupling member to lock the same in a selected one of the folded and unfolded positions.
